    尾叶紫薇与紫薇F1代群体主要表型性状与SSR标记的连锁分析

    Linkage analysis of phonotypic traits of Lagerstroemia caudata and L. indica F1 population using SSR markers.

      摘要
    • 摘要: 以母本尾叶紫薇与父本紫薇‘香雪云’及杂交F1代192株为试材，对株高、地径、叶长、叶宽及叶面积5个性状在群体中的遗传变异进行了统计和分析。结果表明：150对SSR引物筛选出F1群体亲本有多态性的引物对50个； 5个表型性状在群体中呈连续分布，与其正态分布曲线拟合较好，并且彼此之间具有相关性。采用单因素方差分析法进行SSR分子标记和性状的连锁分析得到：SSR3-153、SSR40-131、SSR40-137与紫薇的叶宽显著性相关，贡献率分别为25.5%、12.1%、11.6%；SSR34-158、SSR34-161与紫薇的叶长显著性相关，贡献率分别为7.8%、9.1%；SSR10-172与紫薇的株高和地径显著性相关，贡献率分别为15.7%、10.3%。

       

      Abstract: Hereditary variations of plant height, caliper diameter, leaf length, leaf width, and leaf area of 192 F1 individuals generated from a cross between female L. caudate and male L. indica ‘Xiang Xueyun’ were measured and analyzed. Fifty pairs of SSR primers, which were selected from 150 pairs, showed the polymorphisms on both parents and F1 populations and were used to analyze F1 generation. The results indicated that above five phenotypic traits showed a continuous distribution, fitted better with normal distribution curve, and significantly correlated with each other. Using the single factor variance analysis, linkage between phenotypic traits and SSR markers showed that SSR3-153, SSR40-131 and SSR40-137 significantly correlated with leaf width and the contributions were 25.5%, 12.1% and 11.6%; SSR34-158 and SSR34-161 significantly correlated with leaf length and the contributions were 7.8% and 9.1%. SSR10-172 significantly correlated with plant height and diameter, and the contributions were 15.7% and 10.3%.
